This invention relates to blankets of paper or similar flexible material. r particularly ted, the nvention relates to a practical'and inexpensiv'e'blanket adapted for many'uses, such as a picnic or beach blankehfa rain protector, an automobile'seat protector, and for other diversified uses.

The invention has iorits salient object to Provide a paper blanket that is Vilexible, yieldable, durable and water resistant, and can be QC'OnQmically manufactured, l

7 Another Object of the invention is toiprovide a; simple, practical, economical and ei cieht eth od of" manufacturing a blanket of the character described. 1

Further objects of the invention Will appear from the following description takenin connection with the drawings which form a part of this application, and in which ee a diagr m ic e a ona view illustrating one form of "apparatus IQ! carrying out the-method; F 2 i a n nv ew Qithe ap aratus sho n F g. 3 is a diagrammatic elevat on oft .erig'ht hand end of the apparatus shown in Fig. 2, this view being takenat right anglesto'iFig. 2;' I

The invention briefiy described consists of a blanket formed of relatively heavy crepe paper sheets, impregnated with water resisting material, which are superimposed oneaeh other and are secured together around the-marginal edges thereof lbyisuitable securing and sealing :means.

"character may be used if desiredif may, if desired; be'disposed Io: engagem whe 'rnethojd; consists of superimposing a piural ity of sheets of crepe i ap'er impregna-ted "with water resistant materialisecurin'g and sealing #the v longitudinal edges o'f the; sheets, severing the sheets into predetermined lei-igths, a-nd securing and sealing the transverse edges, the ior'egoing method being carried out as a continuous op'er pea'r'from theiollowingdesoription: r
